Question? Making Bunting

My unit is celebrating its 50th birthday next term, so we'll be having a party. I'd like to make a set of "unit bunting", where the Brownies decorate a flag each. I'm just wondering what is the best way to go about it...

I want to use fabric rather than paper, so that it can be kept and used in the future, perhaps with new Brownies adding their own flags over the years, so need something that's going to last. I also want to be able to use it outside, so it needs to be weather proof.

I've seen plain white bunting flags at Baker Ross, which we could use fabric paints/pens on. Or I thought I could just make the flags myself - maybe from the "honeycomb parc" fabric they have at Fabricland (but not sure if we could paint on this?), which would avoid having to do too much sewing

we made fabric bunting with our Guides. The easiest way we found was getting lots of PVA glue (not the washable version!) diluted it with water put it in a bucket and then dipped the fabric in till it was soaked, then we hung it up to dry - obviously the leaders did this before the meeting, by doing this meant the fabric didn't fray so no seams were needed.
The girls under supervision cut the material into lots of triangles (we used pinking scissors ) and then we purchased some plain white tape about 2 cm wide from our fabric shop. Over a few weeks we had a parent helper and a sewing machine & the girls just stitched the triangles staright onto the tape.

We used Staplers to attach the flags to the tape at the jamboree for ease.

For something different rather than using pens/paint I have seen them done with a very weak water/bleach spray (needs to be darker colour flags) then cut out templates to place on flag. Spray the bleach and water mixture and leave to dry. Remove template. Leaves outline shape of the template in the dark while turning surrounds lighter
